Abstract
For the case study in the Environmental Impact Statement for the Canadian Nuclear Fuel Waste Management Program, segments of the geosphere transport model (GEONET) have been assigned groundwater chemical properties and mineralogical abundances based on data obtained from analysis of groundwaters and rock types in the Whiteshell Research Area. For the groundwaters, salinity and redox conditions range from 0.5 g/L and +200 mV for the shallowest to 25 g/L and -300 mV for the deepest rock layers in the model. The salinity and redox trends of the segments are consistent with observations of other Canadian Shield environments and with concentrations of redox-sensitive species in the groundwater and fracture mineralogy. Modal volume percent of minerals estimated from thin sections of core samples have been used as input data for the same segments of GEONET. The most common minerals include chlorite, muscovite, clays (mainly illite), calcite and iron oxides. In addition, iodide concentrations for these segments have also been determined from available data to provide supporting data for the biosphere transport model (BIOTRAC). The concentrations range from 5 ug/L for shallow to 350 ug/L for deep groundwaters. Likely iodode concentrations for well water or near-surface water discharging into a lake in BIOTRAC
